Every cell in your body has a plasma membrane
, and every membrane can be torn," Dr.
The percentage of motility, live, intact plasma membrane
, capacitation and acrosome reaction of spermatozoa after treatment:
Furthermore, impairments in the calcium sequestration and extrusion pumps of either the ER (SERCA pumps) or the plasma membrane
energy-dependent calcium pumps (PMCA) have reduced activity in aged neurons.
Our results showed that the tested triterpenic acids do affect the permeability of the plasma membrane
, and facilitate the entrance of the molecules, without causing necrotic effects (Mangoni et al.
Spermatozoa morphology, motility, plasma membrane
integrity, acrosome integrity and DNA integrity were evaluated immediately after spermatozoa extraction.
BCECF is a neutral lipophilic form of bis-carboxyfluorescein which diffuses freely through the plasma membrane
This included disorganization of the cytoplasm and loss of organelles, a marked increase in the number and size of lysosomes, the disruption of plasma membranes
, the loss of nuclear membranes, nucleoli, and the fragmentation of condensed chromatin.
pneumoniae is to bind copper ions near the plasma membrane
as soon as they enter the cell and, after diffusion of copper-bound CupA in the membrane, to deliver copper directly to the exporter CopA, which extrudes copper out of the cell.
Recent reports dealing with AQPs, nitric oxide synthase (NOS isoforms) and water permeability show that an NO-mediated pathway results in the insertion of AQP2 from the cytoplasm into the plasma membrane
in the kidney.
The topics include fundamentals of phloem transport physiology, roles of plasma membrane
transporters in phloem functions, sieve element occlusion, the effect of long-distance signaling on development, and the behavioral and molecular-genetic basis of resistance against phloem-feeding insects.
An intact cytoskeletal network, synaptic plasma membrane
proteins, and soluble proteins that are reversibly associated with plasma membrane
proteins are the main requirements of this process.
The ATP2B2 gene codes for a plasma membrane
calcium transporting ATP-ase.
